Growing evidence in the field of child labour has identified social norms among the key antecedents. Social norms regulate actions of people within the social order. Where social norms are institutionalized and legitimized, people conform to them out of a sense of duty. It is argued that legitimate, deep-rooted, and institutionalized social norms are difficult to change. Yet, there have been some significant improvements in research suggesting that normative change programs can effectively shift deep-rooted social norms. In this study, we explored a pathway to change social norms that underpin child labour practices in four major hubs of cocoa and sea fishing. We employed a bottom-up practice research approach to co-design the study, and implemented it through narrative vignette interviews. Using vignette stimulus, we interviewed parents (n = 40), with 20 of them perceived to have engaged their children in child labour, and stakeholders in the communities (n = 10). Findings from the narrative interviews revealed norms on informal apprenticeship, inheriting family business, and hard work, among the core child labour norms. We unraveled the constitutive procedural norms that legitimize and justify the child labour norms in the communities. Based on this, a normative change framework has been designed and supported with suggested intervention programs to shift the social norms.  相似文献

ObjectivesInducing a negative stereotype toward women usually leads to a decrease in women's motor performance. Given that most studies have focused on explicit stereotype induction among adults, the main aim of this study was to investigate the effects of explicit and implicit gender stereotypes on standing long jump performance in children. The second aim was to investigate the effects of these same manipulations on children’s state anxiety.DesignA mixed model design with within-between-subject was used with standing long jump performance and state anxiety as dependent variables.MethodTwo hundred and four children (Mage = 10.95 years, SDage = 0.85) participated in this study and were randomly assigned, after baseline measurement, into four different groups (i.e., explicit/implicit vs. explicit vs. implicit vs. control). Specifically, participants performed 8 trials of standing long jump (4 trials during the baseline phase and 4 trials during the experimental phase). Children also completed the competitive state Anxiety Inventory at baseline as well as immediately after the trials.ResultsFor motor performance, children in the explicit/implicit group and in the implicit group were negatively affected by the stereotype manipulation during all trials whereas participants in the explicit group were only negatively impacted during the last two trials. However, regarding state anxiety, children were negatively affected after both explicit only and implicit only manipulations and more significantly after explicit/implicit manipulation.ConclusionsThe present research showed that the explicit and implicit manipulations influenced motor performance differently, but that these two manipulations increased state anxiety in the same way. Moreover, the combination of the explicit and implicit inductions leads to a greater significant negative influence on state anxiety but not motor performance.  相似文献

The importance of adapting to later life is becoming increasingly apparent to older people as their concerns about health and wellbeing grow. Based on extensive fieldwork between 2020 and 2021 in Guangzhou, China, with older people who consider “singing together in the park” as an essential and popular everyday leisure activity, this article demonstrates how subject (older people), activity (singing), and place (park) integrate into a therapeutic space, the singingscape. Singingscape is presented in three distinct aspects: on the physical level, singingscape indicates an essential embodied experience of the connection between internal body and external environment, from which the older people can relax physically and mentally and acquire a sense of wellbeing; on the social level, singingscape fosters a positive atmosphere, where older people gain a collective sense of belonging and maintain social rhythm and social interactions with their peers; and on the imagined space level, fanciful landscapes and emotional imagination are advantageous to the wellbeing of older people. In the conceptual sense we argue that singingscape is located, experienced and integrated. Lastly, we advocate that attention should be paid to the construction of urban public spaces as vital infrastructure for older people in their everyday leisure activities.  相似文献

外语效应指相比于母语背景,个体在外语背景下风险决策偏差会降低。针对影响外语效应的因素研究大多聚焦于外部因素和与个体外语水平相关的因素,少有研究探讨认知风格的作用。本研究通过524名成人被试,探索认知需求和认知闭合需求对外语效应的影响。结果表明:(1)风险决策中存在外语效应,相比于母语背景,外语背景下框架效应被削弱,且个体更偏向风险寻求。(2)对于认知需求和认知闭合需求都高或都低的个体,语言类型会影响风险决策,在母语环境下倾向于风险规避,在外语环境下倾向于风险寻求;而对于认知需求和认知闭合需求高低不一致的个体,语言类型对其风险决策倾向的影响不显著。本研究为认知风格如何综合影响风险决策提供了进一步的证据。  相似文献

Social science research and clinical literature concur with our experience as providers of psychoeducational and clinical services: Postpartum depression results from the interplay of a multitude of individual and contextual factors. In light of the extensive literature on postpartum depression, it is surprising that models for prevention have not been established. We propose a model for prevention through integrated care and support, in which a wide range of existing services are used. This model is similar to comprehensive prevention models proposed by advocates of integrated service systems, such as community mental health and family support. The article includes illustrative case material.  相似文献

Psychology has not been a visible player in international social and economic development efforts. Through its demonstrated commitment to the concept of quality of life, psychology has an opportunity to help shape foreign policy and to improve the lives of countless people around the globe. Poverty has reached unacceptable limits of humanitarian tolerance and political consequence throughout the world. The United Nations estimates that 20% of the world's population now lives in conditions of absolute poverty in which there is an absence of even the bare essentials for living. Social and economic development efforts have often failed despite good intentions because they have often concentrated on improving peoples' material level of living but not their quality of life. This article addresses the need to include quality-of-life (QOL) indices in international social and economic development efforts. In addition, the article calls attention to the need to use valid cross-cultural measurement strategies (i.e., culturally equivalent) when assessing QOL across cultural and national boundaries. Current approaches to social and economic development rely heavily on interventions that do not reflect the actual peoples' perceptions of life satisfaction and subjective well-being. Self-serving political and economic national interests have kept new approaches to development from being implemented. New interventions must be holistic, decentralized, integrated, empowering, participatory, and human-resource directed, and must include culturally equivalent objective and subjective quality-of-life indices as the arbiters of success.  相似文献

Since blushing is difficult to detect in people with dark skin, their experience of blushing may differ fundamentally from people with fair skin. To investigate this issue, cheek temperature and forehead blood flow were measured in 16 Caucasians and 16 Indians during mental arithmetic and singing. Caucasians (particularly females) thought that they blushed more intensely than Indians, and also reported greater self-consciousness when singing. Vascular responses did not differ between groups. However, skin tone moderated the association between vascular responses and ratings of self-consciousness, blushing intensity, blushing propensity and fear of negative evaluation. These findings support the notion that the visibility of blushing influences the nature of emotions experienced in embarrassing social encounters.  相似文献

Traumatic Brain Injury in School-Age Children Academic and Social Outcome   总被引:1,自引:0,他引:1  
School-aged children with a traumatic brain injury (TBI) require extraordinary effort and energy from individuals in their school, home, and community. The purpose of this study was to examine the academic, behavioral, and social outcomes of a cohort of children and adolescents following TBI. A comprehensive assessment of cognitive functioning, achievement, and adaptive behavior was administered to 43 school-aged children 2 years after their TBI. Premorbid functioning for each participant was obtained from state-mandated test scores assessed prior to the TBI. The predictive utility of premorbid functioning, TBI severity, and age at injury were examined. Findings revealed that premorbid functions were significant predictors of reading and spelling achievement and adaptive functioning. Severity of injury was predictive of adaptive functioning. Implications of findings include program development, reintegration into school, and educating parents and teachers.  相似文献

The results of three experiments are reported. In the main study, a human experimenter presented domestic dogs (Canis familiaris) with a variety of social cues intended to indicate the location of hidden food. The novel findings of this study were: (1) dogs were able to use successfully several totally novel cues in which they watched a human place a marker in front of the target location; (2) dogs were unable to use the marker by itself with no behavioral cues (suggesting that some form of human behavior directed to the target location was a necessary part of the cue); and (3) there were no significant developments in dogs’ skills in these tasks across the age range 4 months to 4 years (arguing against the necessity of extensive learning experiences with humans). In a follow-up study, dogs did not follow human gaze into “empty space” outside of the simulated foraging context. Finally, in a small pilot study, two arctic wolves (Canis lupus) were unable to use human cues to locate hidden food. These results suggest the possibility that domestic dogs have evolved an adaptive specialization for using human-produced directional cues in a goal-directed (especially foraging) context. Exactly how they understand these cues is still an open question. Received: 28 April 2000 / Accepted after revision: 2 September 2000  相似文献

Four jungle crows (Corvus macrorhynchos) were exposed to a mirror placed either vertically or horizontally. The most frequently observed behaviors were pecking at the mirror and wing flapping when looking toward the mirror. These behavior patterns, which were only rarely observed when the mirror was reversed, can be interpreted as aggressive behaviors against a conspecific. The vertical mirror evoked the behaviors more often than the horizontal mirror. The present results suggest that crows perceive their mirror image as an image of a conspecific, not as their own.
